Moving folders/files in the Content Browser sometimes causes a crash

Hello Epic,

so today I loaded the Modular Building System (from the Marketplace) into my project and then I dragged and dropped into a subfolder. Everything worked fine EXCEPT moving the Demo_Scene. When I try moving the Demo_Scene to the subfolder it causes UE4 to break with a big memory leak lol. It uses 7GB of my available 8GB.


Edit: I used version 4.7.0

Yeah, there is a problem when moving scenes imported from packages. It’s been around for quite some time.

The exact same problem occurs also when I copy and paste elements in the UMG editor, although it rarely happens.

Edit: And now it happens also when deleting stuff. The Content Browser seems a bit broken ^^
